What is V-MAP® G3?

Whilst our existing customers are aware that our flag-ship valve monitoring system V-MAP® has been available in the marketplace for around a decade already, in both its first and second generation formats, they are also aware of our continuous improvement culture. In light of this, they requested an enhanced valve condition monitoring solution for safety and process critical valves with the following features and benefits :-

The Need for Valve Condition & Performance Monitoring

Monitoring the condition of critical valves such as Emergency Shutdown Valves (ESDVs), Process Shutdown Valves (PSDVs), High Integrity Pressure Protection Systems Valves (HIPPS), Blow-Down Valves (BDVs) and Pressure Safety Valves (PSVs) on both onshore and offshore Oil & Gas installations, is an essential part of ensuring the safety of personnel as well as the protection of the environment and process plant capital assets.

In today’s process industries, there is an increasing pressure on plant operators and owners to comply with operational safety, quality and integrity standards such as IEC 61508/61511, ANSI/ISA-84.00.01, ISO 55,000, ISO 9001:2015 and of course to respond to (for example) the UK HSE’s recent KP4 Audit findings in relation to ageing and life extension (ALE) – and the continuing safe operation of ageing assets (plant and equipment).

The failure of any Safety Integrated System (SIS) or other critical valve to operate on demand, or fail to provide a shut off, will have a major impact in any process. To demonstrate that all critical valves’ performance meets the installation’s safety criteria, they are normally subjected to routines involving inspection, partial closure, full closure, and leakage tests. These routines often require special test equipment and trained personnel, and will involve an expensive planned shutdown, thereby exposing the owners / operators to safety risks as well as interrupting production / generating losses.

VMap G3 Target

The Score Diagnostics Limited Solution

The need to continuously monitor and assure that critical valves' condition and performance is within the required performance standards is met by Score's integrated V-MAP® G3 system.

V-MAP® G3 is an on-line system that offers continuous, non-invasive valve condition and performance monitoring of critical valves and the process / systems in which they are operating. Performance data is acquired remotely, without the need for personnel to be in attendance to monitor traditional "intervention" type tests. V-MAP® G3 acquires data for every valve operation, including unplanned operations / events, thus building up a history for trending performance, that in some cases may be used in-lieu of a planned intervention test, thereby avoiding the need to interrupt production and suffer losses. Valve and actuator performance trends can then be used to establish a proactive and preventative valve maintenance programme, based on measured in-service valve and actuator condition.

The new and enhanced third generation of the V-MAP® system provides process plant owners, operators, integrity and safety assurance engineers as well as maintenance personnel, actionable evidence and enhanced visibility of any / all developing failure modes in valves and their operators. It covers the Performance Standards for all Safety Critical Elements in Safety Integrated Systems (SIS) : Emergency Shutdown Valves (ESDVs), Process Shutdown Valves (PSDVs), High Integrity Pressure Protection Systems Valves (HIPPS), Blow-Down Valves (BDVs) and Pressure Safety Valves (PSVs).

This approach to valve condition and performance monitoring not only maximises productivity, it significantly improves reliability and reduces risks, thanks to its ability to identify developing failure modes and thus minimise the probability of failure on demand.

V-MAP® G3: The System

V-MAP® G3 dedicated sensors are located on the valve, actuator and on the adjacent piping. The sensor types typically selected are:

The V-MAP® G3 sensors are continuously logged by bespoke data acquisition units (MIDAS® DAUs). On detection of a valve operation, the V-MAP® G3 server either directly outputs results in standalone installations, or - in fully integrated installations – it downloads the information from the MIDAS® DAU and typically requests the following input from the installation's automation databases:

Once the server has collected the raw data from the various sources, it is processed in the Score bespoke Signal Processing Unit (MIDAS® SPU) and stored. The following functions can then be performed to transform the data in to information:
